Enables some higher-level AI behaviour for this force. When set to true, biters belonging to
this force will automatically expand into new territories, build new spawners, and form unit

players who come close.

Note: It is necessary for a force to be AI controllable in order to be able to create unit groups
or build bases from scripts.
